機能説明

The fiocompress utility is a file compression tool that works together with
the dcfs(7FS) file system to perform per-file compression. You can use fiocompress to
decompress a compressed file or mark a compressed file as compressed, causing
automatic decompression on read. The primary use of fiocompress is to compress
files in the boot archive.

Note that this utility is not a Committed interface. See attributes(5).
